Question

Two numbers are in the ratio 5:6, if 16 ip subtracted from each, the numbers will be in the ratio 3:4, if 8 added to the first number and 3 is subtracted from the Second, then they will in the ratio: a) 15:16 b) 14:13 16:15 d) 13:14​

Answer 1

Step-by-step explanation:

x/y = 5/6

x × 6 = y × 5

6x – 5y = 0………………..(1)

If 8 is subtracted from each of the numbers then the ratio is 4:5.

x−8y−8=45

⇒ 5x – 40 = 4y – 32

Then the equation is

5x – 4y = 8……………….(2)

From equation (1)

x = 5y/6

Substituting value of x in equation (2)

5(5y/6) – 4y = 8

y = 48

Substitute the value of y in equation (1) we get

6x – 5(48) = 0

6x = 240

x = 40
